Hi there!

The answer is D.
We need to isolate each square root. We can simply do this by adding \sqrt{4x + 8} to both sides of the equation.

When we isolated the square roots, our equation looks like this:
\sqrt{7x - 7} = \sqrt{4x + 8}

Now we can easily square both sides of the equation, which would have been much harder earlier.

~ Hope this helps you!

What does x equal? Dpsewbskdye
Mice21 [21]

Answer:

x = 7

Step-by-step explanation:

27 = 7x + 6 - 4x      (Given)

27 = 3x + 6             (Simplify)

27 - 6 = 3x + 6 - 6  (Subtract 6 on both sides)

21 = 3x                    (Simplify)

21/3 = 3x/3             (Divide 3 on both sides)

7 = x                        (Simplify)

When Julio cracked open his piggy bank, he
jok3333 [9.3K]

Answer:

52 quarters, 42 dimes

Step-by-step explanation:

Let's call the number of quarters q, and the number of dimes d.

q+d=94

0.25q+0.1d=17.20

Subtract q from both sides of the first equation to isolate d:

d=94-q

0.25q+0.1(94-q)=17.20

0.25q+9.4-0.1q=17.20

0.15q=7.8

q=52

d=94-q=42

Hope this helps!
